To all lwhom it may concern.'

. Be it known that I, PHILIP A. MYERS, a i citizen of the United States, residing at' Ashland, in the county of Ashland and State of Uhio, have invented certain new and useful improvements in Pumps, of which the following is a specication, reference being had therein to the accompanying drawing.

' This invention relates to improvements in pumps' and more particularly to a multiple pump.

The invention consists, essentially, ot' a power head comprising a casing adapted to contain a multiplex power mechanism and a quantity-of lubricant, combined with a multiple pump comprising cylinders with their `pistons and` piston rods, a connection between each piston rod and one branch of the power mechanism and of a Water chamberinto and out ot which the water is drawn and discharged, respectively, by. the pumps.

The invention further consists in so relating and positioning the multiplex power devices with the multiple pumps as that when one pump is about completing its discharge stroke another pump will be still un'- dergoing its discharge-movement and still another pump undergoing its suction movement, so that water is always being drawn into and always being discharged from the water chamber, thus making a perfectly uniform and uninterrupted lowof water, with the result that great quantities are pumped in anygiven space of time, there being no intervals when'the water is not fiowing.

And the invention further consists 'in so relating and combining thispower mechanism, so comprised of the casing and multiplea: power devices with the pump mecha-4 nism comprised ot the water chamber and 'the multiple cylinders, pistons and piston rods, as that both the power-mechanism andv the pumping mechanism will be essentially within the same horizontal level, so that the application of the power to the pumps will be at points low down and near to the pumps, as distinguished from the arrangement in the use ot' 'the usual pump jack or pump head in which the power ot' the pump jack is delivered to the 'pump piston rod. at..

a point high up above the source of' power and the location of the cylinder and piston,

which high up position tends to rockl the structure' laterally, to loosen up the parts and to interfere with smooth operation. l

A nd again, by reason ot this low down position ot' the power mechanism as compared with the location of the pumps l am Y'enabled to carry into effect my seit oiling provision which requires that the casing wrpich conta-ins the oil should be low down o near to the `floor or other support.

signed for use in situations where the waterA supply is say twenty-tive feet or less in distance roin the location of the pumps but where the point of'use of the water is very high above the .location of vthe pumpst, as tor instanpe where the water is pumped from a shallow well under a hotel to be used at points high up in the upper stories of the building or to be deliveied in a high tank.- And likewise for use in mines under similar conditions.

These several objects are carried into practical effect by the multiplex power Amechanism and multipl'e'pumps and. their relative positions, as shown in the accompanying drawings, which are illustrative ot' my preferred, form of construct-ion.

In tle'acc'ompanying drawings: Fig. 1 is a verticahfsectional view ol my multiplex power mechanism and multiple' pumps, the section going through the center of one of the pumps;

Fig. 2 is a diagrammatic view illustrating such position ot the power devices" as will cause one pump to be. completing its discharge of' water, another pump to be in the full action ofA discharging and the third pump in the full action of drawing up water; and' Fi 3 is a transverse sectional'vi'ew on the line 3-3 of Fig. 1 and looking in the direction of the arrow.

The numeral l designates a casing preterablymade ot cast iron and adapted to conu tain both a quantity of lubricant and the power operating mechanism which is to be lubricated and is to perform the functono operating the pump pistons. This casing,v has a removable cover 2 which enables the. ready delivery of lubricant into the casing and the ready placing of the operating mechanism in the casing for purposes ot being assembled.

It also has a vertical slot 3 for presently to a pear.

' In suitable Eearings such as indicated at 4 and 5 in Fig. 3, which bearings are. carried.

a. purpose Again, this apparatus is particularly dellt) by the casing, mount a power driven shaft a projecting arm 29. The slide 221 has, av

6 having a loosepulley 7 and a fixed pulley 8 on which a power belt .is placed, the belt being shiftabl'e from the loose to the tightA and from the tight to the loose pulley. This shaft extends across the casing and is inclosed in an extended sleeve made of sections 9 and 10 and having along its upper surface inclined grooves 11 and 12 which catch the lroppings of lubricant dropping from the mechanism above and convey this lubricant into the bearings. On the shaft is secured.` a pinion 13 which meshes with and rotates-. a driven gear wheel 14.` This wheel 14 is mounted on a shaft 15, mounted in boxes 16, carried by the walls of the` casing. This shaft is rotatable in these boxes or ma -be otherwise mounted if desired.- As ilus- Vand 23, respectively.

trated, the shaft isrotatable andthe gear 14 is fixed to it so that when the gear itself is rotated it carries the shaft. On this shaft are mounted, ixedly,'three eccentrics designated 1T, 18, 19, each eccentric, in its order, being stepped in advance of the other a distance substantially equal to one-third of the circumference, so that the working strokes of these eccentrics will follow one in succession with the other in a manner to produce the relative movements of the pump pistons to be presently set forth.

Each eccentric carries and operates a pitman, the eccentric 17, a pitman 17S, which has a ring-like portion 17b which fits about. the eccentric 17; the eccentric 18, a pitman 18, havin-ga rinmlike portion 18"; and the eccentric 19, a pitnian 2O also having a. ringlike portion 2Oa which tits about the eccentric 19.

Thus when the driving pinion 13 rotates the driven gear 14 these eccentrics and their respective pitmen are also operated. The direction of rotation of the pinion is shown by the arrow in Fig. 1 while the direction bf rotation of the gear 14 is in the opposite direction as shown also by an arrow in Fig. 1. The direction of rotation of the eccentrics is the same as that of the gear wheel 14.

In the casing'there is also secured suitable guides which in the form illustrated consists of shafts or rods 21 22, and 23 secured to the casing at their upper ends by set screws 24 and at their lower ends in sockets 25. On these guides are mounted slides 21a, 2 2,

These slides are adapted to travel .up and down on the guides when they are actuated by the pitinen. The pitnian 17a operates the slide 21 to which it is actuated at its upper bifurcated end by a 'pin 26; the slide 22a is operated by the pitman 18a whose upper bifurcated end is connected to the slide by a pin 27, and the slide 23a is operated by the pitman 20 whose upper` bifurcated end is connected to the slide by a pin 28.

As best seen from Fig. 1, the Slide 23 has projecting arm 30, and'the slide 21 has a projecting arm 31. All of these arms extend through -theslot 3 in the casing. Each` arm is connected tov a separate piston rod-the arm 29 to the piston rod 32-the arm 30 to the piston rod 33-and the arm 31 tothe piston rod 34. Thus when the slides are operated. the piston rods also are operated.

Each piston rod has a piston, such as piston 35, on the rod 32 and each iston is-fitted to a. cylinder, such as cylinder 36 in which the piston 35 operates.

These cylinders, of which there are three, are mounted in a pump head or housing generally designated 37. It is in the form of a hollow casting and contains a water chamber 38, an inlet port 39, and a discharge port 40. A check-valve 41, which closes by grav-V ity, is seated between the inlet port and the Water chamber and opens toward the chamber to `admit water into the chamber from the inlet port. Another check-valve 42, which seats by gravity, is mounted between the water chamber and the, outlet port 40 and unseats toward the port 40 to permit the water to pass from the chamber 38 into and out of theport 40.

From theforegoing detail description it will be seen and understood that my invention comprehends a power headA comprised of a casing anda multiplex power mechanism, andpump mechanism comprised of multiple pumps, and that this union of-the multiplex power devices and multiple pumps produces a very effective pumpingappara` tus by which water is eleva-ted from the source of supply and forced to the place of,

use or collection in a continuous' and uninterrupted stream.

It will be also noted that my invention in cludes a connection between each branch of the power mechanism-an eccentric, its pitman yand the slide-and a piston working in a cooperating cylinder, together with a pump head with its waterl chamber. inlet and outlet ports and valves, which latter several 'elements are common to the several cylinders and pistons.

It will also be understood that my invention comprises thefe-ature of so positioning the branches of the multiplex power devices with relation to the multiple pumps'as that when one pump is completing its discharge stroke, another pump is in the midst ot its pumping stroke, while yet another pump is then undergoing its suction or water lifting stroke, which results in maintaining a contiiiuous inflow of water into the water chamillustrates these relative movements of the multiple pump pistons. In the diagram, the lower eccentric has carriedk its pump piston mi p11 fully through the down-stroke which has its piston on the down-stroke so as to con-Illy tinue the discharge of the Water while the right-handiipper eccentric is still on its upun stroke and is continuing therefore to draw up\\i further supply of water'into the water chamber 3S.'

Thus by my multiplex power devices and my multiple pumps I make a combination pumping apparatus in which I produce the valuable result of a continuous inflow and outflow-n continuous lifting;r and forcing# of water from' the source of supply to the place of 'use y r storage. i

It will sul lilirther be seen that my invention comprehends so positioning the multiplex power mechanism, with its surrounding lubricant casing, with respect to the multiple pumps as that both mechanisms are -in what l may call a low-down position,

both being Vwithin about the samehorizon tal level. This l do in contradistinction from the prevailing plan othav'ng--the power mechanism or power jack extended way above the pump piston and cylinder with the resulting tendency of causing the operating force to produce side motions which rock the structure trom side to side. It is. also to be observed that by reason of this general sameness of horizontal position of the power mechanism and the pump mechanism l am enabled to Carr into eli'ect my self-oiling arrangement which requires that the casing which contains the oil should be low-down or near the place of support; And another advantage of the low-down location ole the power head is that the belt which delivers the power to the driving pulley ot' the head is prevented from the tendency to pull laterally-onv the power head i and tip it over or loosen it from its fastenings.

And finally I would add that this apparatus is particularly designed for use in situations where the water supply is say twenty-tive feet or less in distance from the location ot the pumps, but where the py int of use or storage of the water is very high above the location of the pumps. As for instance. in pumping' water from a shallow well under a hotel to high points of use or storage in the upper stoi'ies or for the deu` movingr downward and the pitmen are in line with the line of movement of the slides on the guides, so that the pull of the pitmen on the slides is then more nearly direct.

The apparatus which is the subject of this specification has been, and now being made.. the subject of commercial manufacture and sale on a large scale at the pump works of my assignee, and has proved to be a highly. satisfactory and useful pumpingi appliance,

so that the statements as toy the mode of operation and results herein made are based upon actual performance of the apparatus6 l/Vhile I have shown and described eccervi trics as` thek means of operating thepitmen v I may employ, within the contemplation of my invention, other means for this pur Again, it will be notedithat there are times when two pistons are traveling upward and drawing water into the water chamber; and

that there are other times when two pistoneare movingr downward and discharging water from said chamber; and that in the first of these situations-the third piston is then on the down-stroke discharging water, and in the second of these conditions the third piston is on the up-stroke drawing` up water.

Having thus fully described my inven-I prising a pump head and multiple pumps,"
